10 * Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel.
12 * At the moment only the 8x16 font is tested and the font fore- and
13 * background color is limited to black/white/gray colors. The Linux
14 * logo can be placed in the upper left corner and additional board
15 * information strings (that normally goes to serial port) can be drawn.
17 * The console driver can use a keyboard interface for character input
18 * but this is deprecated. Only rk51 uses it.
20 * Character output goes to a memory-mapped video
21 * framebuffer with little or big-endian organisation.
22 * With environment setting 'console=serial' the console i/o can be
23 * forced to serial port.
25 * The driver uses graphic specific defines/parameters/functions:
27 * (for SMI LynxE graphic chip)
29 * VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian
30 * VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill
31 * VIDEO_HW_BITBLT - graphic driver supports hardware bit blt
33 * Console Parameters are set by graphic drivers global struct:
35 * VIDEO_VISIBLE_COLS - x resolution
36 * VIDEO_VISIBLE_ROWS - y resolution
37 * VIDEO_PIXEL_SIZE - storage size in byte per pixel
38 * VIDEO_DATA_FORMAT - graphical data format GDF
39 * VIDEO_FB_ADRS - start of video memory
41 * VIDEO_KBD_INIT_FCT - init function for keyboard
42 * VIDEO_TSTC_FCT - keyboard_tstc function
43 * VIDEO_GETC_FCT - keyboard_getc function
45 * CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner.
46 * Use CONFIG_SPLASH_SCREEN_ALIGN with
47 * environment variable "splashpos" to place
48 * the logo on other position. In this case
49 * no CONSOLE_EXTRA_INFO is possible.
50 * CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo
51 * CONFIG_CONSOLE_EXTRA_INFO - display additional board information
52 * strings that normaly goes to serial
53 * port. This define requires a board
55 * video_drawstring (VIDEO_INFO_X,
56 * VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT,
58 * that fills a info buffer at i=row.
59 * s.a: board/eltec/bab7xx.
61 * CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last
62 * character. No blinking is provided.
63 * Uses the macros CURSOR_SET and
